TESTING THE CONCORDANCE OF EVENTS WITH THEIR PROBABILITIES

A test due to D. R. Cox (1958a, 1958b) for the agreement between an observed set of independent events and independently prescribed probabilities is considered. Although the exact distribution can be found for small numbers of events this is often not possible. A method of modifying the scoring system slightly is shown to result in much simpler calculation with very little loss in power. The exact distribution is desirable because of slow convergence to normality. The logic of using a simulation test is considered.     

Results of an Alcohol Prevention Program with Urban American Indian Youth

In comparing alcohol use among American Indian and non-Indian youth, the age at first involvement with alcohol is younger for Indians, the frequency and amount of drinking are greater, and the negative consequences are more common. This article presents the results of an innovative alcohol prevention program for urban Indian youth, blending mainstream prevention approaches with culturally appropriate intervention. A quasi-experimental treatment/non-equivalent control group research design was used to evaluate the Seventh Generation Program, comparing scores over time on measures assessing alcohol beliefs as well as decision-making, social support, locus of control, self-concept, depression, and ethnic identity. Results of repeated measures analysis revealed significant effects for treatment in the areas of alcohol beliefs, social support, locus of control and depression. James R.

Aging and identity in dementia narratives

Abstract

This article explores the way that senile dementia is represented in contemporary culture, with particular reference to texts which narrate the experience of caring for a parent or spouse with one form of the illness. These narratives raise problematic issues about the materiality of the body and its relation to individual identity, and the unstable relationship between memory and identity in postmodern culture, by drawing on the actual experience of bodily dependency and disorientating memory loss in dementia patients. These speculations about the body, memory and the self are ultimately related in narratives of dementia to the inevitable process of aging and dying and the cultural meanings attached to it. The article places the representation of dementing illnesses within a Foucauldian narrative of surveillance and control in the discourse of aging and death in modern Western societies, redemptive views of illness in western culture and arguments about death in contemporary theory.     

Arab students of social work in Israel: adjustment difficulties and coping strategies

Israel is a multi-cultural society, and this can no longer be ignored. However, there is a serious lack of theoretical and empirical literature dealing with the implications of Israel's multi-cultural social context for social work education in Israel, as well as its impact on social work practice with different ethnic and national populations in that country. The dearth of material is even more pronounced in the case of Arab students attending Israeli universities.

This paper documents the first stage of a project focusing on Arab students at the Paul Baerwald School of Social Work at the Hebrew University of Jerusalem. A triangulation method was applied for collection of data from students enrolled in the 3-year programme, graduate students, faculty members and field work supervisors, as well as reports from previous years.

Personal, academic and socio-cultural difficulties are documented as well as coping mechanisms and recommendations for schools of social work in Israel. The results are used to demonstrate cultural misunderstanding, educational dilemmas and differences in professional ideologies.     

Out of Harmony: Health Problems and Young Native American Men

Abstract

Studies of the current health status of healthy young Native American men (American Indians and Alaska Natives) are rare compared with the attention researchers have given the many problems that plague the lives of these young men. Native American men are frequently not included in other studies focusing on men, and information on college-aged, healthy young Native American men is generally not readily available. Despite those drawbacks, this article brings together what is written or known about the health status of young Native American men. The emphasis, based on available information, is placed on some of the major health problems confronting this population.     

Approximation for maximizing monotone non-decreasing set functions with a greedy method

We study the problem of maximizing a monotone non-decreasing function \(f\) subject to a matroid constraint. Fisher, Nemhauser and Wolsey have shown that, if \(f\) is submodular, the greedy algorithm will find a solution with value at least \(\frac{1}{2}\) of the optimal value under a general matroid constraint and at least \(1-\frac{1}{e}\) of the optimal value under a uniform matroid \((\mathcal {M} = (X,\mathcal {I})\), \(\mathcal {I} = \{ S \subseteq X: |S| \le k\}\)) constraint. In this paper, we show that the greedy algorithm can find a solution with value at least \(\frac{1}{1+\mu }\) of the optimum value for a general monotone non-decreasing function with a general matroid constraint, where \(\mu = \alpha \), if \(0 \le \alpha \le 1\); \(\mu = \frac{\alpha ^K(1-\alpha ^K)}{K(1-\alpha )}\) if \(\alpha > 1\); here \(\alpha \) is a constant representing the “elemental curvature” of \(f\), and \(K\) is the cardinality of the largest maximal independent sets. We also show that the greedy algorithm can achieve a \(1 - (\frac{\alpha + \cdots + \alpha ^{k-1}}{1+\alpha + \cdots + \alpha ^{k-1}})^k\) approximation under a uniform matroid constraint. Under this unified \(\alpha \)-classification, submodular functions arise as the special case \(0 \le \alpha \le 1\).     

The effects of human resource systems on operational performance in mass customisation manufacturing environments

This study empirically examines the impact of two human resource management (HRM) systems on operational performance in two distinct mass customisation manufacturing (MCM) environments. Using the survey data collected electronically from 148 mass customisation manufacturers in the USA, moderated hierarchical multiple regression was employed to test the research hypotheses. Results suggest that operational performance significantly increases when a bundle of complementary basic HRM practices are integrated in MCM contexts that emphasise module and process standardisation. This finding indicates that these types of mass customisation manufacturers are capitalising on the opportunity to improve operational performance by strategically combining several different, but supportive, traditional HRM practices with a finite MCM system.     

Oops! and Another Seemingly Four-Letter Word

Performance engineering, SPC, and the Total Performance System are related to one another. Their similarities and differences are noted. Examples of their joint applications are presented in case analyses. It is suggested that we can combine behavior analysis techniques with SPC techniques to construct total performance systems.
